Symptom: The following error message appears Unable to retrieve the schema. Error: An anchor attribute defined by the extension must not be of type Reference or Boolean. A multivalued attribute defined by the extension must not be of type Boolean.

Cause: An error occurred while loading the configuration file. This usually indicates a syntax error in the XML file, which was rejected during validation against the XML Schema. Ensure you are using a XSD-aware XML editor such as Visual Studio, and that the XML file and XSD files are in the same folder while being edited. Check the event log for specific details about the error. Example
The extensible extension returned an unsupported error.
The stack trace is:
"Microsoft.MetadirectoryServices.ExtensibleExtensionException: The schema could not be loaded: The 'object-class' attribute is not declared. ---> System.Xml.Schema.XmlSchemaValidationException: The 'object-class' attribute is not declared.
